NSAlert has: - (void)beginSheetModalForWindow:(NSWindow *)sheetWindow
completionHandler:(void (^)(NSModalResponse returnCode))handler
NSModalResponse has three values: Stop, Abort, Continue - none of which bear any resemblance with the buttons: Default, Alternate, Other in my NSAlert.
Also the actually returned values are not among those in NSModalResponse.
They look like NSAlertDefaultReturn, NSAlertAlternateReturn instead - but this clearly cannot be the case, as these values are deprecated: "These constants are deprecated in 10.9 and will be formally deprecated in the following release"
The suggested alternative is NSAlertFirstButtonReturn, etc., which have values, which very much unlike the actual returned values.
And the header mentions:
"Note that these return values (i.e. NSAlertFirstButtonReturn etc. ) do not apply to an NSAlert created via +alertWithMessageText:defaultButton:alternateButton:otherButton:informativeTextWithFormat:, which instead uses the same return values as NSRunAlertPanel. See NSAlertDefaultReturn, etc. in NSPanel.h"
Which brings us back to the already deprecated values.
I am mightily confused.
Maybe somebody understands this.
Gerriet.
